Italian invasion of Egypt

The Italian invasion of Egypt (Operazione E) was an offensive in the Second World War from Italian Libya, against British, Commonwealth and Free French in the neutral Kingdom of Egypt. The invasion by the Italian 10th Army (10ª Armata) ended border skirmishing on the frontier and began the Western Desert Campaign (1940–1943) proper. The Italian strategy was to advance from Libya along the Egyptian coast to seize the Suez Canal. After numerous delays, the scope of the offensive was reduced to an advance as far as Sidi Barrani and the defeat of any British forces in the area.

The 10th Army advanced about 65 mi (105 km) into Egypt against British screening forces of the 7th Support Group (7th Armoured Division) the main force remaining in the vicinity of Mersa Matruh, the principal British base in the Western Desert. On 16 September 1940, the 10th Army halted and took up defensive positions around the port of Sidi Barrani. British casualties were 40 men killed and the Italians suffered 120. The army was to wait in fortified camps, until engineers had built the Via della Vittoria (Victory Road) along the coast, an extension of the Libyan Via Balbia. The Italians began to accumulate supplies for an advance against the 7th Armoured Division and the 4th Indian Division at Mersa Matruh, about 80 mi (130 km) further on.

On 8 December, before the 10th Army was ready to resume its advance on Mersa Matruh, the Western Desert Force (WDF) began Operation Compass, a five-day raid against the fortified Italian camps outside Sidi Barrani. The raid succeeded and the few units of the 10th Army in Egypt that were not destroyed were forced into a hurried retreat. The WDF pursued the remnants of the 10th Army along the coast to Sollum and across the border to Bardia, Tobruk, Derna, Mechili, Beda Fomm and El Agheila on the Gulf of Sirte. The WDF suffered casualties of 1,900 men killed and wounded during Compass and took 133,298 Italian and Libyan prisoners, 420 tanks, over 845 guns and many aircraft.
